A preliminary deal to sell 36 A380s to Emirates blew up in an Airbus hospitality chalet moments before the Gulf carrier was expected to shower $30 billion on the plane maker and its U.S. rival Boeing at the start of last week¡¯s Dubai Airshow.

Two top Emirates officials broke the news to Airbus CEO Tom Enders and his sales chief, John Leahy, that the widely expected $16 billion deal would not be signed that day, leaving uncertainty over the future of the world¡¯s largest jetliner.

The halt came so swiftly that Airbus PR executives who were already in place for a double-signing ceremony a hundred yards away found themselves awkwardly among the audience as Boeing walked away with the sole Emirates order, worth $15 billion.
